Windows Ce Compact Framework HttpWebRequest

Question

我试图使用rest api在controller上写一些数据。

但是奇怪的事情正在发生。 前1、2、3次写入很好，但是比应用程序冻结并获得超时异常时，我是否未关闭某些内容？

这是下面的code ：

        WebRequest client = (read) ? HttpWebRequest.Create(ReadUri) : HttpWebRequest.Create(WriteUri);
        client.Method = "POST";
        client.ContentType = "application/json";
        CredentialCache creds = new CredentialCache();
        creds.Add(new Uri(WriteUri), "Basic", new NetworkCredential(*******));
        client.Credentials = creds;
        client.PreAuthenticate = true;
        ((HttpWebRequest)client).AllowWriteStreamBuffering = true;
        client.Timeout = 10000;
        //Skipped all data formatting
        byte[] data = Encoding.UTF8.GetBytes(req);
        client.ContentLength = data.Length;
        Stream dataStream = null; 
        try
        {
            //HttpWebResponse response = (HttpWebResponse)client.GetResponse();
            dataStream = client.GetRequestStream();

            dataStream.Write(data, 0, data.Length);
            dataStream.Flush();
            dataStream.Close();
            dataStream.Dispose();
            dataStream = null;

        }
        catch (WebException we)
        {
            string message = we.Message;
        }
        finally
        {
            client = null;
        }

发送请求后，应处理响应并进行处理。 如果您不这样做，那么请求及其响应仍将与连接保持关联，并且.NET默认情况下仅具有几个可用于WebRequest的连接。

...
dataStream.Close();
dataStream.Dispose();
dataStream = null;
using (HttpWebResponse response = (HttpWebResponse)client.GetResponse())
{
}
